IMPROVEMENT IN REFRIeRATINeTRANSPORTATION-CASES.

Specification forming part of Letters Patent No. 198,124, dated December1l, 1877 lapplication filed October 13, 1577.

To all whom it may concern:

Be it known that I, RESTORE B. LAMB, of the city and county of Camden,and State of New Jersey, have invented a new and useful Improvement inRefrigerators for Transporting Fruit, Vegetables, Ste., whichimprovement is fully set forth in the following specification andaecompan ying drawings, in which- Figure 1 is atop view, partly brokenaway, of the refrigerator open, embodying my invention. Fig. 2 is avertical section thereof in line a: x, Fig. 1. Fig. 3 is a side view ofone of the spring-platforms.

Similar letters of reference indicate corresponding parts in the severalgures.

My invention relates to a refrigerator adapted for the transportation offruits, berries, vegetables, &;c., the same having a lining of paper,which prevents the escape ofthe cold air and entrance of heat, and beingalso provided with a series of elastic platforms arranged within themain compartment around the ice-box, and adapted for the protectivesupport of the more delicate fruits, substantially as hereinafter setforth and claimed. l

Referring to the drawings, A represents the case of the refrigerator,the sides of whose inner face are lined with paperB,between which andthe walls of the case there are secured, at intervals, cleats C, whichleave air-spaces ct between the case and lining, and support the lining.The cover D and bottom of the ease are also lined with paper, as at B.Within the case there is supported an upright ice or refrigeratingchamber, E, having al id, against which the cover D may bear, and abottom opening for escape of the water of the melted ice.

perishable articles, are placed within the case A surrounding thechamber E, the latter being properly filled with ice or otherrefrigerating substance, and the cover Dis then closed and secured, andin this conditionthecaseand its contents may be readily transported.

It will be seen that the lining B is agood non-conductor of heat, and itcauses the retention of the cold air within the case. It is easilyworked, as it were, and applied. It is light and cheap, and the cold-airspace is dry,

The fruit, berries, vegetables, or other likeV anditis easily cleansed,whereby a cheap, light,

convenient, and reliable refrigerator for transb1 at the vertical jointbetween the central depending part of the cover and inner walls of thecase, and when the cover is closed, said extension b2 rests on the topF, thus closing the horizontal j ointof the cover and walls, and as thecoverwill close on the case witha snap, the several joints will be tightand secure.

For the shipment of delicate articles, such as early strawberries, Iemploy elastic platforms G, consisting of bearing-pieces supported onsprings placed within the case on thebottom thereof. These platforms, asshown in the accompanying drawing, consistof upper and lower strips,withintermediate springs, the width of the strips being equal to thewidth of the space between the ice-box E and the inner walls of therefrigerating-compaitment. As shown in Fig. l, the upper strips of thisseries of spring-platforms surrounding the icechest constitute a.continuous bottom, the dividing-lines ofthe same being indicated at g,in which the said lines are represented as radiating from the fourcorners of the ice-box. By this arrangement a better protectivesupportwill be afforded for the fruit than if the same wereformed in anunbroken surrounding strip. The paper lining B will also be protectedfrom injury from the boxes, which, without the spring-platforms, wouldfrequently oc- C111'.

The boxes of berries or fruit will be placed on the platforms and packedin tiers, or otherwise disposed in the case to fill the cold-air space,and the yielding nature of the platforms prevents shaking, jarring, &c.,to which the case will be subjected in transit, materially disturbingthe contents of the boxes.

The platforms are made detachable from the case, so as to be removedwhen not required, and for purposes of cleansing and repairs.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination, with the refrigeratorcase A, 'and a centralice-chest, E, of the series of spring-platforms G, arranged around thechest so as to constitute a continuous spring bottom between the sameand the lining B, the said independent platforms thus constituting acontinuous bottom, being adapted to serve as protective supports fordelicate fruits during transportation, as herein shown and described. v

2. In combination with case A, provided with 'i a paper lining,B,'secured at b by strips F, the cover D, with paper lining extendingvertically upward at b, and horizontally outward at bz upon therabbetedunder edge of the said cover, which forms a close joint with theparts F and b, all as herein shown and specified.

RESTORE B. LAMB.
